What are the key features of OPA2846IDRG4?
- Dual voltage-feedback op-amp in single 8-pin SOIC package, halving board space compared to two single op-amp devices
- 110 dB typical common-mode rejection ratio (90 dB minimum) for superior noise rejection in differential signal paths
- 760 µV maximum input offset voltage enabling precision DC-coupled amplifier stages without excessive output error
- Wideband architecture supports high-speed applications such as ADC drivers and active filter stages
- Internal frequency compensation reduces external component count and simplifies PCB layout
What is OPA2846IDRG4 used for?
OPA2846IDRG4 is used in differential signal amplification, instrumentation front ends, and active filter circuits where low noise and high CMRR are required to reject common-mode interference. Its dual channel configuration suits balanced audio amplifiers, optical receiver transimpedance stages, and medical imaging signal chains that need two matched amplifier channels in a compact footprint. The wideband voltage-feedback architecture also makes it suitable for high-speed ADC input buffer designs in industrial measurement systems.

Frequently Asked Questions
What CMRR does OPA2846IDRG4 achieve and why is that important for differential signal amplification?
OPA2846IDRG4 achieves 110 dB typical CMRR with a minimum of 90 dB. This high rejection ratio suppresses common-mode noise on differential inputs by a factor of over 100,000 times, making it well-suited for instrumentation amplifier front ends and precision measurement systems operating in electrically noisy environments.
What is the input offset voltage of OPA2846IDRG4 and how does it affect DC-coupled designs?
OPA2846IDRG4 specifies a maximum input offset voltage of 760 µV. In a DC-coupled gain stage with a gain of 10, this offset produces a maximum output error of 7.6 mV, which must be budgeted against the system's allowable DC error in precision sensor or instrumentation applications.
How many amplifier channels does OPA2846IDRG4 contain and what is the package?
OPA2846IDRG4 contains 2 independent op-amp channels (dual) in an 8-pin SOIC (SOIC-8) package, providing two matched voltage-feedback amplifiers in a single compact SMT device. This reduces board area compared to using two separate single-channel op-amps while sharing power supply decoupling components.
For which high-speed signal chain stages is OPA2846IDRG4 a strong candidate?
OPA2846IDRG4 is a strong candidate for ADC input buffer stages, active anti-aliasing filters, and optical receiver transimpedance amplifiers where wideband low-noise voltage-feedback operation is needed. Its 90 dB minimum CMRR and 21.2 µA maximum bias current suit both DC-coupled differential and single-ended high-speed signal paths in industrial and medical measurement equipment.
